The aim of the study was to design and fabricate a LED based solar simulator to match the full solar spectrum of natural light. The finding of this research can be applied in the field of solar energy as it can be utilised in testing photovoltaic technology (PV). To achieve this objective, the researcher focused on selecting appropriate LEDs to match the solar spectrum and intensity, whilst also designing the LED solar fabricator and testing the temporal drift of the simulator’s spectrum and power distribution. The key hardware requirements were LEDs and LEDs drivers which were chosen based on their sizes and dimensions in addition to the degree to which they could match the solar spectrum. In selecting the driver, avoidance of Arduino was a key consideration. The software EasyEDA was utilised in creating printed circuit boards (PCB) while wavelength was measured by employing the Ocean view spectrometer. The results of the LED solar simulator were tested against the solar simulator class A of the American Society for Testing Materials (ASTM). The overall objective of the research to design and fabricate a LED solar simulator was achieved as the solar simulator successfully simulated the full range of visible light in the solar spectrum.

However, due to the limitations of the spectrometer, ultraviolet and infrared light was not able to be simulated. Another principal discovery of the research conducted was that a closer match to the solar spectrum was attained where there were sufficient LEDs to maintain a small as possible gap between the light wavelengths. A further finding was that the light concentrator designed and constructed by the researcher was crucial to achieve the required mixture of light. In conclusion, the study highlights the fact that higher efficiency of LED solar simulators can be achieved through tuning the intensity, classification, size and uniformity of the wavelengths to match the solar spectrums.
